You know you're an Engineer when...

You take building your son's train track seriously and want to make it the best damn train track your son has ever seen.

Train set up #1

Train set up #2

Train set up #3 - This one he kept up and intact for a few days, that's saying a lot for a three year old.

I personally think this one is the best.

Yep I'll just go ahead and pat myself on the back. The key, have a lot of train tracks to work with :)
